SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1140 AM CDT Tue Jun 17 2025 Valid 171700Z - 181200Z ...CRITICAL FIRE WEATHER AREA FOR WESTERN NEW MEXICO AND FAR EASTERN ARIZONA... No significant changes in the previous forecast were needed. Enhanced mid-level flow associated with an upper-level short wave trough in conjunction with a deep/well-mixed boundary layer will promote a broad fire weather threat across the Southwest through today. Relative humidity at or below 10 percent and west winds of 20-25 mph atop dry fuels will support Critical fire weather conditions across far eastern Arizona into western New Mexico and Rio Grande Valley. ..Williams.. 06/17/2025 .PREV DISCUSSION... /ISSUED 1256 AM CDT Tue Jun 17 2025/ ...Synopsis... A midlevel trough will move eastward from the Great Basin into the central Rockies today. Within the base of the trough, a belt of moderate deep-layer westerly flow will overspread the Southwest into the southern Rockies. In response to the eastward-moving trough, a lee cyclone will deepen over the central/southern High Plains, while a southward-extending dryline sharpens over the southern High Plains. ...Western NM and eastern AZ... In the wake of poor overnight recoveries, strong diurnal heating/mixing of a dry antecedent air mass west of the dryline will yield widespread single-digit RH across much of AZ and NM during the afternoon. Substantial boundary-layer mixing into the enhanced deep-layer flow, coupled with a tightening pressure gradient peripheral to the lee cyclone, will support 20-25 mph sustained westerly surface winds amid the low RH and hot surface temperatures. This combination will favor critical fire-weather conditions atop dry fuels in western NM and far eastern AZ. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
